It’s ideal for digital signage, education, business, or media setups where flexible installation is a must.

Seamless Signal Transmission with Low Latency

This HDMI wireless receiver with KVM functionality offers near-zero latency over the 5 GHz band. It uses dynamic frequency selection (DFS) and automatic channel switching to avoid signal interference. As a result, it delivers a smooth and stable wireless HDMI experience. You get consistent video and real-time control, even in busy wireless environments.

Multiple Receiver Support for Broad Distribution

The GF-EXT-WiK-5G-RX allows one Transmitter to connect with multiple Receivers. This makes it great for systems that require wireless HDMI KVM delivery to several displays or control points. Built-in EDID management and plug-and-play setup simplify integration. LED indicators make diagnostics fast and clear during installation.

Compact Form Factor for Versatile Installations

With a slim, low-profile build, this wireless KVM-over-HDMI receiver fits neatly behind displays or into AV racks. It includes IR passthrough and can be powered via USB or external supply. Paired with the matching Transmitter, the 4K Wireless HDMI KVM Receiver provides a reliable, modern way to extend HDMI and USB signals up to 100 feet—without clutter or complexity.
